When a charged particle enters a uniform magnetic field what is its kinetic energy?

When a charged particle enters a uniform magnetic field, its kinetic energy remains constant. Force is perpendicular to the velocity, so the work done by magnetic field is Zero. This does not cause any change in kinetic energy. Hence, option (a) is correct.

What happens to Ke of charged particle moving in uniform magnetic field?

The kinetic energy will also remain constant . So there will be a Lorentz force acting and hence the particle will undergo uniform circular motion , the particle will accelerate and the momentum will also change not in magnitude but in direction . The kinetic energy will remain constant .

When a charged particle moves perpendicular to a uniform magnetic field its energy and momentum?

In a circular path direction of the velocity continuously changes, So the direction of momentum will also change. So When a charged particle moves perpendicular to a uniform magnetic field, its momentum changes. Hence the correct answer is option 1.

When a charged particle enters a uniform magnetic field perpendicularly its path is?

Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. The particle continues to follow this curved path until it forms a complete circle.

When a charge enters a uniform magnetic field the charge?

A charge in a uniform magnetic field will undergo uniform circular motion. The force is perpendicular to the charge’s motion, because →F=q→v×→B. That means that no work is done on the charge. No work done on the charge means that the charge’s kinetic energy remains constant.

When a charged particle moves perpendicular to a magnetic field it suffers a change in its?

Acceleration of the particle remains unchanged.

When a charged particle moves through a magnetic field perpendicular to its direction?

When a charged particle enters a magnetic field at a direction perpendicular to the direction of motion, the path of the motion is circular. In circular motion the direction of velocity changes at every point (the magnitude remains constant). Therefore, the tangential momentum will change at every point.

What is the path of a charged particle in a uniform magnetic field if its velocity is not perpendicular to the magnetic field?

If a charged particle moves in a region of a uniform magnetic field such that its velocity is not perpendicular to the magnetic field, then the velocity of the particle is split up into two components. One component is parallel to the field while the other component perpendicular to the field.

When a charged particle enters in uniform magnetic field its acceleration?

When a charged particle enters, parallel to the uniform magnetic field, it is not acted by any force, that is, it is not accelerated. Thus, its speed remains constant, and so does its kinetic energy.

When a charged particle moves perpendicular to a uniform electric field its?

Its momentum changes, total energy is same.

What happens to energy when a charged particle enters a magnetic field?

If a charged particle enters perpendicularly in the uniform magnetic field then (1) Energy remains constant but momentum changes (2) Energy and momentum both remains constant (3) Momentum remains constant but energy changes (4) Neither energy nor momentum remains constant Sol.

What happens to energy and momentum in a uniform magnetic field?

If a charge particle enters perpendicularly in the uniform magnetic field, then: energy and momentum both remains constant energy remains constant but momentum changes both energy and momentum changes

Why is magnetic force perpendicular to the direction of motion?

Another way to look at this is that the magnetic force is always perpendicular to velocity, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected but not the speed.

Is momentum constant throughout the trajectory of a particle?

As momentum is a vector quantity so momentum is not constant throughout the trajectory but magnitude of the momentum will be constant i.e. at each point of the trajectory momentum will have two components which will vary with time in such a way magnitude of the momentum remains same.
